在我的Velocity模板我创建的地图是这样的： 

#set($mymap.Map={"key":"value","key2":"value2"})

我认为，必须根据速度的文档工作，但有一个错误： 

HTTP Status 500 - Could not load Velocity template for URL [editEmployee.vsl]; nested exception is org.apache.velocity.exception.ParseErrorException: Lexical error: org.apache.velocity.runtime.parser.TokenMgrError: Lexical error at line 44, column 36. Encountered: "{" (123), after : ""

type Exception report

还有就是我的聚甲醛与速度： 

<dependency>
            <groupId>org.apache.velocity</groupId>
            <artifactId>velocity</artifactId>
            <version>1.6.2</version>
        </dependency>   
        <dependency>
            <groupId>velocity-tools</groupId>
            <artifactId>velocity-tools</artifactId>
            <version>2.0</version>
        </dependency>
        <dependency>
            <groupId>velocity-tools</groupId>
            <artifactId>velocity-tools-generic</artifactId>
            <version>1.4</version>
        </dependency>
        <dependency>
            <groupId>commons-collections</groupId>
            <artifactId>commons-collections</artifactId>
            <version>3.1</version>
        </dependency>

Answer 1:

据说这是在速度工作。 我尝试以下简单片断，无论是在1.7和1.6.2，并且打印正确的响应： 

#set ($mymap = {})
#set ($mymap.Map={"key":"value","key2":"value2"})
$mymap

打印： 

{Map={key=value, key2=value2}}

因此，请确保该错误确实是在这里：

  1. 并建议错误位置（第44行，36列），匹配你报行？
  2. 如果您注释掉该行是否错误依然？
  3. 是否与其他组件从春节前处理模板，从而使最终的速度看到另一件事比你所认为的呢？
    • 如果你的代码有一些空格重新格式化是否错误依然？
  4. 如果使用这种替代语法是否错误依然？ 
#set($discard = $mymap.put('Map', {'key':'value','key2':'value2'}))


Answer 2:

尝试

#set($mymap={"key":"value","key2":"value2"})     
$mymap
